A clinically documented 12-week journey of post-operative recovery following triple-vessel coronary artery bypass grafting, managed through multidisciplinary home healthcare in Patna, Bihar.
Registration No.: RMC-79836 | Internal Medicine & Geriatric Medicine Specialist
This case study has been clinically reviewed and documented for educational purposes. All clinical decisions referenced reflect evidence-based post-CABG rehabilitation protocols.
Patient Profile
Mr. Devendra Narayan Singh, a 64-year-old retired Public Works Department (PWD) Executive Engineer, had been living a relatively sedentary post-retirement life in Patna, Bihar. His daily routine involved limited physical activity, occasional morning walks in his neighborhood park, and managing household affairs. As a former civil engineer who spent decades overseeing large infrastructure projects across Bihar, he was accustomed to a structured and disciplined lifestyle, which later proved advantageous during his recovery.
His wife, Mrs. Usha Singh (60), served as the primary caregiver at home, while his younger son, Mr. Ankit Singh, a mechanical engineer living in Patna, provided secondary support and coordination with healthcare providers. The family structure ensured that there was always someone available to monitor the patient, manage medications, and accompany him during rehabilitation sessions. This availability of capable family caregivers was an important factor in the treating cardiologist’s decision to recommend a home healthcare program rather than an extended hospital stay or rehabilitation facility admission.
The patient carried multiple comorbidities that significantly elevated his cardiovascular risk profile and required simultaneous management during the post-operative recovery period:
The combination of long-standing hypertension, diabetes, dyslipidemia, and obesity created a high-risk metabolic environment that not only contributed to the development of triple-vessel coronary artery disease but also complicated the post-surgical recovery process. Each of these conditions required independent monitoring and management, making a multidisciplinary patient care approach essential rather than optional. The presence of a trained home nurse who could simultaneously track blood pressure, blood sugar levels, wound healing, and medication compliance was therefore a clinical necessity — not merely a convenience.
Mr. Singh developed sudden severe chest pain while walking in his neighborhood park. The pain was typically anginal in character — a crushing, pressure-like sensation that radiated to his left shoulder and jaw. This radiation pattern is clinically significant because it indicates cardiac ischemia rather than musculoskeletal or gastrointestinal causes. The pain was accompanied by profuse sweating (diaphoresis), breathlessness, and nausea — all of which are classic features of acute coronary syndrome.
His family immediately recognized the severity of the situation and transported him to a tertiary cardiac care hospital in Patna. This rapid response was critical, as delays in seeking care for acute coronary syndromes are associated with significantly worse outcomes. At the hospital, an emergency coronary angiography was performed, which revealed extensive triple-vessel coronary artery disease — meaning all three major coronary arteries supplying the heart muscle showed significant blockages.
Clinical Reasoning: Why Triple-Vessel CABG?
When coronary angiography reveals significant disease in all three major coronary arteries (the left anterior descending, left circumflex, and right coronary artery), the treatment decision between percutaneous coronary intervention (PCI/stenting) and coronary artery bypass grafting (CABG) depends on several factors. In this case, the extent of disease (triple-vessel involvement), the anatomy of the blockages, and the patient’s diabetic status collectively favored surgical revascularization. Multiple clinical trials, including the SYNTAX and FREEDOM trials, have demonstrated that diabetic patients with triple-vessel disease have significantly better long-term outcomes with CABG compared to PCI. The off-pump technique was chosen to reduce the risks associated with cardiopulmonary bypass, particularly given the patient’s age and comorbidities.
Primary Diagnosis
Triple-Vessel Coronary Artery Disease — Significant atherosclerotic narrowing of all three major coronary arteries Acute Coronary Syndrome — Presenting with typical anginal chest pain with radiation and autonomic symptoms Post Off-Pump CABG Status — Three coronary artery bypass grafts placed to restore myocardial blood flow Associated Conditions: Hypertension (18 years), Type 2 Diabetes Mellitus (10 years), Dyslipidemia, Obesity (BMI 29 kg/m²)
Presenting Condition After Hospital Discharge
Upon discharge from the hospital after 15 days, Mr. Singh’s condition was stable from a surgical perspective, but he exhibited several expected post-operative findings that required structured management. It is important to understand that “stable” at discharge does not mean “recovered.” The patient was in the early phase of a recovery process that would take weeks to months:
Mild discomfort around the surgical incision during movement — typical of median sternotomy healing
Significant deconditioning from 15-day hospitalization and the physiological stress of major surgery
Reduced exercise tolerance with minimal exertion — a common finding in early post-CABG recovery
Noticeable after climbing one flight of stairs — reduced cardiopulmonary reserve post-surgery
Could walk approximately 120 meters independently before needing to rest
Understandable psychological response to major cardiac surgery; reduced confidence outdoors
Mr. Singh was admitted to a tertiary cardiac care hospital in Patna where he underwent a comprehensive diagnostic and therapeutic workup. The total hospital stay lasted 15 days, which is within the expected range for a patient undergoing triple-vessel CABG with multiple comorbidities.
Emergency Coronary Angiography
Performed on arrival to visualize the coronary anatomy. This invasive imaging study confirmed significant stenosis in all three major coronary arteries, establishing the need for surgical revascularization over stenting.
Off-Pump Triple-Vessel CABG Surgery
The surgical team performed coronary artery bypass grafting on a beating heart (off-pump technique), creating three bypass grafts to redirect blood flow around the blocked segments. The off-pump approach was selected to avoid the inflammatory response and complications associated with cardiopulmonary bypass.
ICU Monitoring and Stabilization
Post-operative care in the cardiac ICU included continuous cardiac monitoring, hemodynamic stabilization, pain management, and close observation for any immediate surgical complications such as bleeding, arrhythmias, or graft failure.
Respiratory Physiotherapy and Incentive Spirometry
Initiated early in the post-operative period to prevent pulmonary complications. The median sternotomy incision causes significant pain with deep breathing, leading patients to take shallow breaths. Chest physiotherapy is a critical component of post-CABG care.
Early Mobilization Program
Progressive mobilization from bed rest to sitting, standing, and walking was initiated under supervision. Early mobilization reduces the risk of deep vein thrombosis, prevents muscle deconditioning, and accelerates functional recovery.
Medication Optimization and Discharge Planning
Before discharge, the cardiology team optimized the medication regimen including antiplatelet therapy, beta-blockers, ACE inhibitors, statins, antidiabetic medications, and antihypertensives. Nutritional counselling and cardiac rehabilitation education were provided. The team then recommended a structured home healthcare program.

The decision to recommend home healthcare was not based on patient preference alone — it was a clinically reasoned recommendation driven by the specific needs of this patient’s post-operative condition. Discharging a post-CABG patient home without professional support carries well-documented risks, particularly when the patient has multiple comorbidities.
Post-CABG patients are discharged with a median sternotomy incision that takes 6 to 8 weeks for initial healing. During this period, the incision requires daily assessment for signs of infection. The patient’s diabetic status further elevated the infection risk, as diabetes impairs wound healing and immune function. A trained home nurse could perform daily wound assessments that a family member is not qualified to perform. Additionally, the patient was on multiple cardiac medications — antiplatelets, beta-blockers, statins, ACE inhibitors, antidiabetics, and antihypertensives — each requiring specific timing, dosing, and monitoring for side effects. Medication management in a polypharmacy patient requires clinical training.
While the home nurse provided clinical care during scheduled visits, the patient needed continuous supervision during activities of daily living. The risk of falls is significantly elevated in post-CABG patients due to orthostatic hypotension, generalized weakness, and reduced balance. A fall onto a healing sternum could cause catastrophic wound dehiscence. The patient attendant provided this continuous safety net while also offering emotional support — an often underestimated but clinically meaningful component of cardiac recovery.
Fifteen days of hospitalization combined with the physiological impact of major cardiac surgery resulted in significant physical deconditioning. Without structured physiotherapy at home, this deconditioning would progressively worsen. Cardiac rehabilitation physiotherapy follows a carefully graded protocol that progressively increases exercise intensity while continuously monitoring for warning signs. Physiotherapy also addressed shoulder mobility — a commonly overlooked issue in post-CABG patients.
The first three months after CABG surgery represent the highest-risk period for complications. Weekly doctor home visits allowed the cardiologist to assess surgical recovery, monitor heart function, review medications, evaluate exercise tolerance, and detect complications at the earliest possible stage. This proactive approach is a well-established principle in post-hospital discharge care.
Managing a post-CABG patient with hypertension, diabetes, and obesity requires regular objective data collection. A blood pressure monitor, pulse oximeter, glucometer, incentive spirometer, and digital weighing scale transformed the home from an unmonitored environment into a clinically equipped recovery setting.
The following multidisciplinary home care plan was designed and implemented based on the treating cardiologist’s recommendations, the patient’s clinical status at discharge, and evidence-based post-CABG rehabilitation protocols.
Home Nursing
Patient Attendant
A trained patient attendant was present throughout the day for continuous safety supervision. Trained attendants play a critical role in post-surgical recovery:
Physiotherapy and Cardiac Rehabilitation
The physiotherapy program followed a structured, progressive protocol aligned with Phase II cardiac rehabilitation guidelines. Customized rehabilitation is essential for every post-CABG patient.
Graded walking program to progressively increase aerobic capacity within safe heart rate limits
Incentive spirometry, diaphragmatic breathing, thoracic expansion exercises. Chest physiotherapy protocols
Addressing stooped posture and shoulder stiffness from internal mammary artery harvest
Everyday movements — chair rises, stair climbing, safe bending — modified for sternal precautions
Written and demonstrated exercise plan for patient and family to follow between sessions
Weekly Doctor Home Visit
Comprehensive cardiac examination including auscultation for new murmurs or gallop rhythms Assessment of surgical wound healing progress Review and adjustment of multi-drug medication regimen Evaluation of exercise tolerance progression Review of BP and blood sugar logs maintained by home nurse Early detection of arrhythmias, pericardial effusion, wound infection, or cardiac decompensation
Medical Equipment at Home
Equipment arranged through medical equipment rental in Patna:
Structured Daily Care Plan
Daily inspection for redness, discharge, warmth, or wound separation. Diabetes increases this risk.
Post-CABG atrial fibrillation is common in the first 2-4 weeks. HR and rhythm monitored daily.
Daily assessment for pedal edema, weight gain, breathlessness at rest, and orthopnea.
Twice-daily monitoring; both hypertension and hypotension are concerns.
Fasting and post-prandial monitoring; surgical stress can worsen glycemic control.
Leg swelling, pain, or redness monitored. DVT prevention is critical.
Temperature, cough assessment, and SpO2 tracking to detect pneumonia early.
Monitoring for bradycardia, dizziness, bleeding, and muscle pain from multiple medications.

Driving not yet cleared No lifting >5-10 kg Strenuous activities not cleared Full sternal healing may take 3-6 months
Mr. Ankit Singh (son): “We knew our father needed professional support after such a major surgery, but none of us had the medical knowledge to monitor his vitals, assess his wound, or manage his multiple medications. Having a nurse, physiotherapist, and doctor coming to our home gave us a level of confidence we could never have achieved otherwise.”
Mrs. Usha Singh (wife): “I was constantly worried about him falling or overexerting himself. Knowing that someone trained was with him during his walks allowed me to rest without guilt.”
Taking all cardiac medicines exactly as directed — correct doses, timing, never skipping without medical advice.
Low in saturated fat, salt, and processed foods. Rich in fruits, vegetables, whole grains, and lean proteins. Nutrition’s role in disease prevention is a long-term strategy.
No lifting heavy objects until cleared. Correct techniques to help the patient without stressing the healing sternum.
Remind and encourage incentive spirometry several times daily — essential to prevent lung complications.
Using BP monitor, glucometer, and weighing scale. Maintaining logs for review during nurse and doctor visits.
Increasing walking distance gradually based on physiotherapist’s recommendations — not pushed beyond advised levels.
Severe chest pain, sudden breathlessness, irregular heartbeat, fainting, wound redness/discharge, high fever, or leg swelling. Emergency warning signs guide
Attending all scheduled cardiologist visits. Follow-up care breakdown is a documented cause of preventable readmissions.
The 250% improvement in walking distance was the direct result of a structured, progressive rehabilitation protocol initiated within the first week. Research demonstrates that early cardiac rehabilitation reduces mortality by 20-25% and significantly improves functional capacity. The home setting, when supported by trained professionals, removes the barrier of travel while the patient is still recovering.
The first 72 hours after discharge are the highest-risk period. The home nurse’s presence ensured vital signs tracking, correct medication administration, professional wound assessment, and established escalation protocols — fundamentally different from a family member “keeping an eye” on the patient. Early warning sign recognition requires clinical training.
Poorly controlled blood sugar would impair wound healing. Uncontrolled BP would stress grafts. Unmanaged dyslipidemia would continue atherosclerosis. The home healthcare model allowed all conditions to be monitored simultaneously — difficult to achieve in fragmented OPD-based follow-up. Chronic disease management at home provides this integrated approach.
Post-CABG pulmonary complications are among the most common readmission reasons. The patient’s excellent SpO2 (consistently 98%) and zero pulmonary complications directly attribute to consistent incentive spirometry compliance. Chest physiotherapy should be standard in every post-CABG home care plan.
Post-cardiac surgery depression and anxiety affect 20-40% of patients and are associated with poorer rehabilitation adherence and higher readmission rates. By Week 4, the patient’s anxiety had noticeably resolved — consistent with expected psychological adaptation when adequate support is provided. Mental health in senior years deserves equal clinical attention.
The optimal model is professional care augmented by family support, not family care substituted for professional care. Why family care alone is often insufficient is a critical distinction for families to understand.
Post-CABG readmission rates in India are 12-18% within 30 days. The zero readmission outcome was the result of systematic surveillance, early intervention, medication optimization, and patient education — representing significant economic value compared to each avoidable readmission costing ₹1-3 lakhs.
Weekly doctor visits provided longitudinal assessment by the same physician tracking subtle trends. A BP of 140/90 in isolation might not concern a busy OPD, but when the same physician has tracked 120/76 over previous weeks, this elevation becomes significant. This continuity is one of the most underappreciated advantages of doctor home visit services.
